The D50VS High-Vacuum Mini Gas Pump delivers industrial-grade reliability for demanding applications, combining high vacuum (-91kPa), large flow (13L/min). Its modular design features swappable nozzles and 90° rotatable ports for flexible installation, while optional PTFE corrosion-resistant materials (diaphragm, valves, seals) ensure compatibility with aggressive gases.

 

High Vacuum,Large Flow Rate

Featuring industrial-grade vacuum performance, this mini gas pump achieves an ultimate vacuum of -91kPa (100 mbar.abs) and a peak flow rate of 13L/min . Its balanced high-vacuum and high-flow design caters to critical processes like gas sampling, analytical instrumentation, and automated systems where both speed and suction depth are essential.

Modular Connections

This mini gas pump offers comprehensive connection compatibility with multiple standard fitting options including 8mm and 4mm hose connector,quick-connect PC6 and PC8, , as well as internal threaded Rp1/8 and NPSC1/8 connections.

High Airtightness

The pump offers superior airtight performance D50TS with an optional stainless steel pump head specifically engineered for high-seal applications, featuring an extremely low gas leakage rate to ensure reliable operation in demanding environments.

Multiple motor options

The pump is available with two motor options to meet different application requirements: a brushed motor version offering excellent cost efficiency for general-purpose use, and a brushless motor variant that delivers superior longevity (8,000+ hours continuous operation) with minimal maintenance needs.

High Corrosion Resistance

The pump features excellent corrosion resistance, with optional PTFE (Teflon) diaphragms and valve seals specifically engineered for handling aggressive gas media. This chemical-resistant configuration maintains performance when pumping corrosive vapors or acidic gases, making it ideal for laboratory, industrial, and chemical processing applications where material compatibility is critical.

Long Lifetime

The mini gas pump offers service life with 2,500 hours for brushed motor versions and up to 8,000 hours for brushless motor (BLDC) models, ensuring long-term reliability for different operational needs.

Advanced Multi-Protection System

This model features intelligent self-protection with stall protection, over-current protection, and reverse-connection protection. This comprehensive safety system actively prevents damage from high-load conditions, power supply faults, or operational errors, ensuring uninterrupted performance and extended service life.

Industrial-grade Reliability 

In response to industrial-grade reliability requirements, we have designed a special test process for possible load conditions. Therefore, no matter what load the product actually works under, its actual service life can reach and exceed its nominal service life. If the actual working load is less than the nominal maximum load, its life can be further extended. Therefore tt can operate without stopping for a long time under the maximum load. The product has passed the life test under the maximum load, and can promise to reach the nominal life under various loads.

Speed Control Function 

The mini gas pump’s flow rate can be adjusted by controlling the motor speed. For brushless motor (BLDC) models, speed regulation is achieved by adjusting the PWM duty cycle. For brushed DC motor versions, motor speed control and consequently flow control can be accomplished either by varying the input voltage or through PWM control using an H-bridge circuit.
